Markus, i would agree to move to WSPR-32 now.
Same QRG. Will be interesting to see the new spectrograms and the
possible distances!

Assume that you and Markus will be operational in WSPR-32 during the
overnight as well? If you can, please TX running until shortly after
your sunrise.

CFM, i will run the TX until 6 UTC in WSPR-32 mode on 136.164 kHz.
My part is the first 30 minutes of each hour. This can be nicely seen
on the grabbers,

;arkus starts to transmit right after i have finished my last
transmission.
An hour ago there was a very exciting funny race for me. I had to
modify the watchdog circuit to allow a longer transmit time. This had
to be finished before the next full hour starts. I took a micro-switch
on the board and increased the R likewise from 560 k to 560+1500k Ohm.
Soldering, drilling holes, connect 7 RG174 signal cables and the power
supply, setting up the PC to generate the signal, giving power to the
PA, all in 15 minutes ;-) I won the race but there was a bug anyway,
somehow. Thus the time constant still was at 9 minutes and so my first
attempt was negative. But the seconds was a nice success, as reported
by Terry.
